I agree with both points here which is why I created
bin/maint/exampleslog.py  which is now in master but not
hooked up in runhtml.py or linked to from the nightlies.

The idea of this is that it assigns responsibility
by the last committer of a given example.  While this is
obviously not perfect, if someone edited an example recently,
they are in the best position to take a quick look at what
the problem is (hence, saying it assigns responsibility and
not blame since you don't know where the blame lies).

This would allow a distribution of responsibility rather than just 
having a single person have to do everything, and doesn't require
a huge paradigm shift.
